Best ResponseYou've already chosen the best response.1h = 0 when it hits the ground, therefore: 16t^2 + 48t = 0 ... Factor out 16t 16t(t + 3) = 0 : Two solutions t = 0, when it begins it's upward journey and t = 3 sec, when it returns to earth

Best ResponseYou've already chosen the best response.0when the ball hits the ground h = 0 so we have 0 = 48t  16t^2 solve for t one of the solutions will be 0 corresponding to start of the kick The other one will be you answer.
